Abstract:
PURPOSE:The Wnt pathway plays an important role in embryonic development, and defects in this pathway have been implicated in the tumorigenesis. The Dickkopf 3 (DKK3) is a putative Wnt signaling inhibitor that is frequently inactivated in human cancers. However, the expression of DKK3 in ovarian cancer remains unknown. METHODS:We investigated the expression of DKK3 in silico using the Digital Differential Display. DKK3 mRNA expression was also analyzed by real-time RT-PCR in ovarian carcinomas and normal ovarian tissues. DKK3 protein expression was determined by immunohistochemistry in the same ovarian carcinomas and normal ovarian tissues. RESULTS:A significantly reduced expression of DKK3 (P < 0.05) was found after comparison of normal ovary- and tumor-derived libraries in the Cancer Genome Anatomy Project (CGAP). DKK3 mRNA expression was reduced in 63% (35 of 56) of tumors compared with normal ovarian samples (P < 0.02). Analysis of 13 matched pairs of ovarian carcinomas and adjacent normal tissues showed significant transcriptional downregulation of DKK3 (>twofold) in 9 paired carcinomas (69%). Loss or weak membranous expression of DKK3 protein was observed in 66% of ovarian cancers (37 of 56) including all tumors with low transcriptional level of DKK3 gene analyzed by real-time PCR. CONCLUSIONS:To our best knowledge, this is the first time to demonstrate altered expression of DKK3 in ovarian cancer. The latter could be a relevant mechanism for the activation of the Wnt pathway in the carcinogenesis of ovarian cancer but additional studies are required to elucidate the function of DKK3 silencing in ovarian carcinogenesis.
